Roblox operates a free-to-play online video game platform with nearly 150 million daily active users. This platform has spawned a virtual universe and a Roblox economy based on the Robux currency. The platform houses millions of games from a wide range of creators—spanning from young gamers themselves to professional development studios. Roblox offers creators the tools, publishing abilities, and platform for their games, enabling anyone to create a game. Creators earn money when gamers make optional in-game purchases within their games and by offering space for real-world advertising, and Roblox earns revenue primarily by taking a cut of these earnings.
